package/parted: fix static link

libuuid needs to be linked with -lintl when gettext is needed (with
locales).

For a shared build, this is solved with the DT_NEEDED ELF tags, but for
a static link, it is not pulled in automatically.

Use pkg-config to find libuuid, instead of AC_CHECK_LIB().

Second part at fixing:

+configure: use pkg-config to find libuuid
+
+In some conditions, libuuid may be linked with -lintl. This can be the
+case on uClibc when locales are enabled.
+
+When doing a shared link, this dependency is automatically pulled in via
+a DT_NEEDED ELF tag
+
+For a static link, there is no such mechanism to pull in dependent
+libraries.
+
+Currently, the check for libuuid is done with AC_CHECK_LIB, but this
+does not handle dependencies, and thus a stattic build fails.
+
+Use pkg-config to find libuuid, that automatically pulls in the
+dependencies of libuuid, if any.

+
+---
+Note: of course, that relies on the fact that libuuid installs a proper
+.pc file; a patch will be submitted upstream shortly.
+
+But even considering the current situation, where libuuid does not
+provide a proper .pc file (yet), this patch does not change the
+behaviour we've had so far; it is a bet on the future! ;-)
